My favorites in no particular order (and sorry, I haven't seen enough to give you ten in several different genres...I guess I'm boring that way)

The Hunting PartyOscarItalian JobThe Transporter (the first one)Series of Unfortunate EventsHarold and MaudeGods and MonstersThe Secret GardenEver AfterAll three Jason Bourne movies (is that cheating?)

No particular order: Evil Dead II, Suspiria, Inferno (by the way, why did Argento direct that "The Mother of Tears" crap? one of the worst movies ever), Snatch, Cannibal Holocaust, Audition, Tetsuo the Iron Man, Seven, Johnny Got His Gun, and most of Fulci's stuff. And tons of others.

A Top Ten Movie List is it? Very well then.The Wild BunchThe Royal TenenbaumsThe Maltese FalconCool Hand LukeThe Big SleepRide the High CountryRaiders of the Lost ArkCasablancaLawrence of ArabiaOnce Upon a Time in the West

No particular orderPan's Labyrinth Braveheart Lonesome DoveWatership Down (where else can you see animated rabbits cursing and ripping each other apart)Shadow of the VampireBut I'm a Cheerleader (as sappy as the pooka gets)Batman (while it's got issues, I can't get enough of Jack Nicholson as the Joker...)American PopRocky Horror Picture ShowHellraiser 3 (can't get enough pinhead either...)

In more or less correct order...Many of these I've seen at a second-run theater at midnight, which is the best way to see most of them, I believe.

1) Donnie Darko - no movie has affected me in quite the same way, and at the same time immediately put Mary McDonnel and Jake Gyllenhaal on my favorite actors list2) Eternal Sunshine of the Spotless Mind - Jim Carey is, I think, one of the best actors in Hollywood, but unfortunately you don't see him do this very often. Simon Birch is the other one I can think of off the top of my head.3) Brazil - The art design, the writing, the sheer silliness at parts, and the fragility of the movie blends into an extremely touching film4) Fear and Loathing in Las Vegas - I must have watched this movie at least ten times my first year at college. I've come to realize I spend an awful lot of time in Bat Country, and I've never done drugs in my life.5) Clerks - One of the most quotable films of all time, and the first movie that I really sat down to analyze. It was great fun then, and it still is whenever I watch it.6) The Empire Strikes Back - The definition of the 1980s, as far as I'm concerned. 7) The Boondock Saints - The first time I saw this movie it set my Irish blood boiling. It is still simmering.8) Serenity - I'm a browncoat through and through, so this movie was candy for me. Bitter, sour candy with at least three razor blades hidden in it, but candy nonetheless.9) Once Upon a Time in the West - Singlehandedly made me fall in love with westerns.10) Ghost in the Shell - Singlehandedly made me fall in love with cyberpunk.
